Loose ball joint

72 Cuda. While replacing the upper control arm bushings with offset ones I discovered the ball joint is loose. It won't tighten, one is stripped. What are my options? Oversized joint, new arms, welding?

speedway and other vendors have a weld in replacement part....

Doctor Diff has a pair of brand new UCA's loaded for under $100. Not even worth messing with the old stuff at that price.

Dr. Diff looks like the way to go, do the Moog offset bushings fit in these? And is that for a pair?

Yes and yes

Ordered, Thanks

The ball joints are self tapping. Another option is to add some metal back to the socket with a welder, grind out the excess and then use the ball-joint to re tap the threads. I used that method on my driver's side UCA, works well.

Thanks for the idea Chris but already ordered the new arms.
